No personal attacks! Yes, you can call someone out and tell them they screwed up, or call them a dumbass (it's part of the trade), but don't get carried away. This is kind of a generic rule, and it is up to the moderators/admins to enforce as they see fit.

No pornographic material! No exceptions! If you have doubts about whether you should share it, you probably shouldn't. In most cases, you'll get 1 strike for this, and on strike 2 you'll be banned.

Post in the correct forum. For the love of all that is holy, post things where they are intended to be posted.
